I've had the same problem testing rails. It only seems to glitch when the player rides the minecart. If he doesn't ride, the glitch doesn't start. Version 1.4.4.
I added screenshots with the newest snapshot showing the fps with and without the walls. The client is not modded, but the problem still persists when there are a lot of cobblestone walls stacked together, getting worse with a bigger stacking.
Yes I had mcpatcher installed and didn't realize this was a mod, sorry about that. However the problem still persists without any mods, the new (green)pictures use snapshot 13w04a, without mods.
It does, but it takes a riduculus amount of cobblestone walls to get me down to half fps on a superflat world. I added pictures. More like, I added cobblestone walls until I started "double-placing" them.

The leaves break stairs too.
Creepers, skeletons, sheep etc. except for spiders are all affected by this glitch.
I've only been on a single player instance and even the normal texture pack and client causes lag with fences and walls in the pattern.
I have seen the glitch actually, in 1.4.6, I haven't noticed it in the newest snapshot yet though.
